2 Application filed August 1, 1908. Serial No. 446,477.

To all whom it may concern.-

Be' it known that I, HowARo T. HAL- LOWELL, a citizen of .the- United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in t haft- A further object of my invention is to provide a shaft collar made up of a pair oi cupped shells or sections of similar contour with retaining means to which they are riveted for holding the same together; such retaining means being preferably an annular band, continuous or otherwise, and properly dispostcl wit-lrregard to the shells or sections forming the collar.

My present invention, which is, in part, a division of my application for patent filed March 20, 1908, Serial No. 422,318, pat ented Aug. 4, 1908, No. 895,409,) refers particularly'to structures secured together by means of an annular hand riveted to a pair of sections of the same contour, having; peripheral walls or flanges with adjacent or abutting edges. forming the collar, though. as will be readily understood, other means of securing said band to the sections to maintain then in proper relative position may be employed and they are within the scope of my invention.

These and other features of my invention are more fully described hereinafter, reference being had to the accoi'npanying drawings. in Wl'l'lOllZ' Figure l, is a vertical sectional view of a shaft collar embodying my invention; Fig. is a sectional view of the same, taken on the line (1 0, Fig. 1; Fig. 3, is a plan view of thestructure shown in Figs. 1 and 2, and FigsJl and are views illustrating details of my invention.

The structure forming the subject of my invention comprises a. plurality of sections or blanks of sheet metal pressed into shape to\form an annular member with shaft engaging portions the sections of such member bEHIg PIOVlClGd with peripheral 'walls forming" a shaft engaging sleeve. The structure so made incloses a hollow annular space; the sections forming the same being so disposed as to provide inutual connection and sup-port and-havingportions of the metal comprising the s'arne displaced so as to confine in proper relative position, a suitable nut "for the set screw' employed with such collars. i

In the structure shown in Figs. 1 and 2, I provide a pair of members, L-shaped in cross-section, which are combined and secured together to form an annulus or collar. These sections have side walls 1,with Out u'ardly extending offset portions 2, and innor peripheral walls or flanges 3; In order to secure this collar together, I provide an annular band orsleeve 4 disposed in such position with regard to the sections as to form a hollow annular space-between it, the side walls, and the inner peripheral walls or SYLVANIA, A 0011mm flanges of said sectionsfsuch sleeve or band being" apertured at 5 for the passage of a set screw 6 which enters a. not 7 disposed in the hollow annular space and confined in proper relative position. In order to confine the sections of the collar in position by the annular sleeve. the latter is provided with spnds 8 arranged to enter apertures 9 in the offset portions 2 of the side walls of the sections and be riveted thereto, in the manner clearly shown in the drawings, such action binding the sections together and holding then against displacement. If

desired. the sleeve or band 4 may be brazed, electricallvweidcd. or otherwise permit nently secured to the sections.

The securing sleeve or band 4 is continu ous and may be formed into the necessary shape from a fiat strip. the meetii g ends'or edges of which abut and may or may not be secured hv bra zinc or other desirable means. Tn addition this band is provided with the bent up portions 10 which form guards" for the head of the set screw. These bent up portions may alsoextend inwardly from the sleeve or band 4 so as to provide portions 11 for engagement with the sides of the nut and retain the latter in proper place. As n additional retaining means for the nut, e inner peripheral wall of the collar adjacent the aperture for the set screw 1s struck up at 12 to form projections to pgage themut.
